Dental anatomy exhibits considerable variation with the presence of additional canals being a common occurrence. The upper second molar typically presents with three canals and three roots; however, variations such as the existence of an extra canal or a root can pose challenges during endodontic treatment. Maxillary molar is characterized by an additional canal located within the palatal root, often exhibiting complex configurations and variations in morphology. Access refinement is critical to gaining adequate visibility and facilitating instrumentation. Meticulous exploration of the pulp chamber floor and careful examination of radiographs from different angles are essential for accurate diagnosis. Careful negotiation and cleaning of the extra canal with appropriate files and irrigants are essential to remove pulp tissue and debris effectively. Furthermore, obturation of the canal space with biocompatible materials is crucial to ensure a three-dimensional seal and prevent bacterial ingress. Clinically, the inability to detect and treat the extra palatal canal can lead to persistent infection, incomplete debridement, and compromised treatment outcomes. This case report delves into the significance of this anatomical variation, diagnostic modalities, and effective management strategies.

Background: The deep inferior epigastric perforator (DIEP) flap is currently the gold standard for autologous breast reconstruction. In cases where the DIEP is contraindicated, the profunda artery perforator (PAP) flap is now the preferred second-line option in our institution. The PAP flap poses unique challenges to the reconstructive surgeon, especially in Asian women with low body mass index (BMI).

Background: Predictors of difficult fiberscopic intubation have not been fully elucidated. This study focused on identifying radiographic predictors of difficult fiberscopic intubation during general anesthesia in patients with a cervical collar.
Methods: This retrospective study included unconscious patients who underwent orotracheal intubation using a flexible fiberscope while wearing a cervical collar to simulate a difficult airway.

Background: Obesity has been associated with human obstructive sleep apnoea and canine brachycephalic obstructive airway syndrome. The effect of body condition score (BCS) on structures of the oropharynx, nasopharynx and upper airway of the horse has not been investigated.
Objectives: To investigate the effect of BCS on tongue measurements, soft palate angle and basihyoid depth in horses.

Background: Clinical and epidemiological analyses have found an association between coronavirus disease 2019 (COVID-19) and knee osteoarthritis (KOA). Infection with COVID-19 may increase the risk of developing KOA.
Objectives: This study aimed to investigate the potential causal relationship between COVID-19 and KOA using Mendelian randomization (MR) and to explore the underlying mechanisms through a systematic bioinformatics approach.
